}

Keyshare for refresh of a party.

Fields

rank_list: Vec<u8>

Rank of each party

threshold: u8

Threshold value

public_key: ProjectivePoint

Public key of the generated key.

s_i: Option<Scalar>

set s_i to None if party_i lost their key_share

x_i_list: Option<Vec<NonZeroScalar>>

set s_i to None if party_i lost their key_share

lost_keyshare_party_ids: Vec<u8>

list of participants ids who lost their key_shares, should be in range [0, n-1]

party_id: u8

Part ID from key share

Implementations

impl KeyshareForRefresh

pub fn new( rank_list: Vec<u8>, threshold: u8, public_key: ProjectivePoint, root_chain_code: [u8; 32], s_i: Option<Scalar>, x_i_list: Option<Vec<NonZeroScalar>>, lost_keyshare_party_ids: Vec<u8>, party_id: u8, ) -> Self

Create new KeyshareForRefresh object.

Warning

It is recommended to use KeyshareForRefresh::from_keyshare() and KeyshareForRefresh::from_lost_keyshare() instead. This is for advanced usecases only.

pub fn from_keyshare( keyshare: &Keyshare, lost_keyshare_party_ids: Option<Vec<u8>>, ) -> Self

Create KeyshareForRefresh struct from Keyshare

pub fn from_lost_keyshare( rank_list: Vec<u8>, threshold: u8, public_key: ProjectivePoint, lost_keyshare_party_ids: Vec<u8>, party_id: u8, ) -> Self

Create KeyshareForRefresh struct for the participant who lost their keyshare

pub fn to_bytes(&self) -> Vec<u8>

Serialize KeyshareForRefresh to bytes Used to send KeyshareForRefresh to other parties, for key-import

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Deserialize KeyshareForRefresh from bytes

Trait Implementations

impl Clone for KeyshareForRefresh

fn clone(&self) -> KeyshareForRefresh

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeyshareForRefresh

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Zeroize for KeyshareForRefresh

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
